解説TlI(331.29).タリウムとヨウ素を加熱して直接反応させると得られる.α,β形の2変態がある.α形は赤色の結晶.165 ℃ 以上で安定である.融点440 ℃,沸点824 ℃.融点近傍で超イオン伝導体となる.α形を冷却すると165 ℃ でβ形の黄色の結晶に転移する.室温ではβ形が安定である.水に難溶.TlIを少量加えたNaI結晶は,いちじるしい蛍光を発するので,シンチレーターとして放射線検出器に用いられる.そのほか,高輝度放電灯にも用いられる.有毒.[CAS 7790-30-9]森北出版「化学辞典(第2版)
使用Thallium(I) iodide is used in mercury lamp to enhance its performance. It is mainly used for underwater lighting, since the blue green light produced has least absorption in water. Scintillator made by using iodide salt of thallium, sodium and cesium is utilized for radiation scintillation detectors.
純化方法Reflux it for 2-3hours with water containing HI, then wash it until acid-free, and dry it at 120o. Store it in brown bottles. [D.nges in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 870 1963]. POISONOUS.
